We find boundary confining dualities of 3d N = 2 supersymmetric gauge theories with exceptional gauge groups.

Boundary confining dualities and Askey-Wilson type q -beta integrals (2023)
Journal Article

We propose confining dualities of N
= (0, 2) half-BPS boundary conditions in 3d N
= 2 supersymmetric SU(N), USp(2n) and SO(N) gauge theories. Some of these dualities have the novel feature that one (anti)fundamental chiral has Dirichlet boundary... Read More about Boundary confining dualities and Askey-Wilson type q -beta integrals.

We examine the dynamics of noncommutative instantons of instanton number 2 and commutative instantons of instanton number 3 in 5D super Yang-Mills theory. We begin by detailing the construction of the 1=4-Bogamolyni-Prasad-Somerfeldt instanton soluti... Read More about Notes on the dynamics of noncommutative U(2) and commutative SU(3) instantons.

It has been previously shown that a Gauss–Bonnet term nonminimally coupled to a scalar field produces a scalarised black hole solution which can be considered as having secondary scalar hair, parametrised in terms of the black hole’s mass and charge....

We construct Seiberg-like dualities of 3D N ¼ 2 general quiver gauge theories with unitary, symplectic, and orthogonal gauge groups coupled to fundamental and bifundamental matter fields.

We derive general BPS boundary conditions in two-dimensional N = (2, 2) supersymmetric gauge theories.

We study a U(N |M ) supermatrix Chern-Simons model with an SU(p|q) internal symmetry.
